Explain how inhalation and exhalation change the volume pressure. There are several limitations, systematic and random errors that should be considered when interpreting these results. Emphysema causes alveolar dilation and destruction of alveolar walls which causes an increase in residual volume with air that cannot be exhaled. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor.

As well as the chamber size increasing as a result of endurance training. Explain why the atria have thinner walls than the ventricles of the heart. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. Explain why the residual volume of the lungs does not change with exercise. Fill in the blank. Fiber adsorbs (binds) bile so eating a fiber-rich (high fiber) diet would result in more bile binding to fiver and more bile excreted in feces. of course the minute ventilation increase tremendously after exercising.

Why does a lack of ATP cause muscles to stay relaxed or contracted? VC is the the most volume of air that be be released from your lungs after you take the biggest breath you may physically be able to. What is the basic difference between a lung volume and a lung capacity? Taking part in regular aerobic exercise has been shown to increase a person's vital capacity. An asthmatic has a normal lung size so vital capacity is normal but narrowed airways make FEV1 low, The maximum amount of air someone is able to move in and out of lungs in one minute. resulting in an increase in pulmonary ventilation. This means there is more oxygen circulating in the blood for the tissues to take up. Describe and explain alveolar pressure change as the diaphragm flattens and the intercostals muscles contract. Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. Then indicate the way in which who or whom is being used in the Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals.
